Geometry Perimeter & Area of Similar Figures

In this lesson we are going to go over perimeter and area of similar figures. If you remember from similar polygons, they have a ratio, a scale factor. A scale factor is the same thing as ratio of the corresponding parts, a : b. If two figures have a scale factor of a : b, then the perimeters of the two figures will also be a : b. The areas of similar figures are also in proportion, which you'll learn in this lesson. To understand all of this better, you'll get to practice through the extra examples provided.

*These practice questions are only helpful when you work on them offline on a piece of paper and then use the solution steps function to check your answer.
